Water Test Kit
Instructions
The WATER TEST KIT can be used to determine the percentage
of water in various fluids. Typically these fluids are hydraulic and
lubrication oils; however, other fluids can also be tested. The
WATER TEST KIT has five ranges from .005% to 12% water.

Instructions
Caution:
Using the water test kit can be dangerous!
You must read and understand the following precautions
before you begin to use the water test kit!
WARNING:
The packets of Reagent A in this kit contain Calcium Hydride which can
cause eye and skin burns. Calcium hydride, in contact with water, will
produce hydrogen gas which is highly flammable.
Avoid getting the chemical on your skin or in your eyes. Keep the kit and
Reagent A away from water and water vapor. DO NOT use the kit near
an open flame or sparks. DO NOT permit smoking when the kit is being
used.
Never use more than one packet of Reagent A per test. Excessive hydrogen
gas could be produced causing injury to you or damage to the test vessel.
FIRST AID:
In case of contact with Reagent A powder, immediately flush eyes or skin
with water for at least 15 minutes. Remove contaminated clothing. Wash
skin contact area with soap and water. Call a physician.

Water Test Kit
Instructions
Water Test Kit can be used to test for water content measured as Parts Per Million
or as a % of volume. The test can be performed on any liquid which is not based
on water. On the lower two ranges, the direct reading gauge displays from 50 to
15000 Parts Per Million (.005% to 1.5%), with a resolution of 20 PPM (.005%) water.
Any fluid can be tested as long as the two following requisites are met: A, the water
MUST be in the form of free molecules or droplets and not be chemically or physically
bound as in emulsions; B, the fluid should not attack the water vessel components
which are anodized aluminum, fluorocarbon gasket, brass, and the epoxy used to
mount the Reagent Chamber.
Principle of Operation
Reagent A reacts with water and produces hydrogen gas. When a sample
and a dry solvent (Reagent B)
are placed in the vessel in the proper
ratio, the pressure produced is proportional to the amount of water
present. A sample with .1% (1000 PPM)
water content will produce 10 pounds
per square inch (PSI) @ 25° C. Since the
pressure gauge has a full scale value of
15 PSI, a maximum reading of 0.15%
(1500 PPM) water is possible on the low
range. The smallest division of the gauge
on the PSI scale is 0.2 PSI or .002% (20
PPM). The gauge’s pointer can easily
point to the space between the smallest
divisions, thus providing the ability to
read a result down to the nearest 0.001%
(0.1 PSI) or 10 PPM of water. There are
a total of five ranges with the following
full scale values: 0.15%, 1.5%, 3.0%,
6.0%, and 12.0%.
CAUTION:
When releasing pressure from the vessel
via the “Pressure Relief Button,”
DO NOT aim the discharge spray at
your face or eyes!
When using the test vessel, the operator
should make sure the pressure does not
exceed 15 PSI, since over-pressurizing
the gauge will damage it. Should you
encounter a sample with a water content
which will produce a pressure equal to
or greater than 14 PSI, release the pressure immediately. The preferred procedure is to watch the gauge as the reaction takes place, observing the pressure.
When the pressure reaches 14 PSI, intervene and stop the test by pressing
the relief valve or loosening the lid.

Test Procedure
.15% Full Scale
1 Using the 30 ml syringe, measure 30 ml of sample oil and inject it into the OilReagent B Chamber. Be careful not to spill any fluids into the Reagent A
Chamber.
2 Using the 10 ml syringe, measure 10 ml of Reagent B and inject it into the
Oil-Reagent B Chamber.
3 Prepare a packet of Reagent A (according to the Reagent A Instruction sheet).
Empty the rolled-up packet of Reagent A into the Reagent A Chamber, being
careful not to spill any powder into the Oil Solvent Chamber. Place the rolledup packet with the open end facing down, into the Reagent A Chamber and
flick the bottom of the packet a few times with your finger.
4 Keeping the cup vertical so as not to spill or mix the contents, tightly screw
the cap onto the cup making sure there is a very tight seal on the gasket.
5 Shake the vessel vigorously for 20 seconds, then observe the pressure gauge
to insure that the pressure has not exceeded 14 PSI. If the pressure has reached
14 PSI, STOP the test by pressing the relief valve or loosening the cap. Go
to the next section titled “1.5% Full Scale” for instructions on testing samples
with water content greater than .14%.
6 Shake the vessel vigorously for another 20 seconds, and then observe the
pressure gauge to insure that the pressure has not exceeded 14 PSI.
7 Shake the vessel vigorously AGAIN for another twenty seconds, observing
the pressure gauge to insure that the pressure has not exceeded 14 PSI.
8 Set the vessel down and wait one minute. Shake the vessel for 10 seconds
once every minute and take the final reading 5 minutes after you have started
the test.
9 Measure the temperature of the oil-Reagent B mixture and refer to the
temperature compensation chart to correct the reading due to the effects of
temperature.
Reading the Gauge
Correlation of Data: Low Range –
Multiply the Gauge Reading by 0.01
10.0 PSI = 0.100% water content or 1,000 PPM
1.0 PSI = 0.010% water content or 100 PPM
0.2 PSI = 0.002% water content or

For example, let’s say that after

Should the reading on the gauge exceed 14 PSI again, stop the test and prepare
a new test using 1 ml of sample and 19 ml of Reagent B. Using the following
equation, determine the percentage of water:
Water % = Gauge Reading x .4
Example: gauge reads 11.5 PSI

Beyond 12% Water Content
It is possible to measure water content above 12%. The accuracy will depend on
your laboratory technique and should be within 5 to 10% of reading. The technique
used to prepare the sample is known as serial dilution. The process involves taking
a sample with high water content and diluting it with a dry solvent. The resulting
mixture is a sample with water content in the range of the Water Test Kit (WTK).
This diluted sample mixture is tested using the WTK and the results are multiplied
by a known factor to arrive at the original sample’s water content.
The chart below shows how to take a high water content sample and make an
approximate 2% sample for testing on the WTK’s 3 % range. The chart also shows
the multiplication factor needed to convert the results of the 3% range test back
to the original sample’s water content. The following is an example of the process.
Process Example
For this example, we use an oil sample with an assumed water content of 35%. In
the chart below, go down the first column labeled “% Water in Sample” to 35%.
In the second column labeled “Sample”, you will see that it directs you to take 2.9
ml of the high water content sample and mix it with 47.1 ml of dry solvent. Mix the
diluted sample (DS) well and then perform the 3 % range test which is found on
page 7 (i.e. Take 2 ml of DS and 18 ml of Reagent B). In this example the gauge
reading will be 10 PSI.
Water % = gauge reading x .2 (10 PSI x .2 = 2.0%). To convert the results of the 3%
range test back to the original sample’s water content, multiply 2% x 17.5 (the factor
listed below at 35 % level). 2 x 17.5 = 35%
